Voice is now available in your existing Codex threads. Talk through a PR with the agent that wrote it, debate the architecture, or work out what comes next. You can jump into voice whenever something needs a back-and-forth, then let the agent keep working once you’ve figured it out together.

This is GPT-6 Astra.

Anything you can do on a computer, Astra can do for you. Fast.

[Thomas Ricouard @Dimillian]

Astra is very good at 3D modeling, and I can't wait for all of you to experience it, for now here is a little walkthrough on how I built the demo house for our launch blog post. From a Blender scene to a Unreal Engine 5 walkable experience. 🧵

[Tibo @thsottiaux]

We are starting to release GPT-6 Astra and we are doing it as carefully and quickly as possible. It was very important to us that we bring it to all Plus users and not only Pro, Business and Enterprise.

It will take a few days for the rollout to complete and behind the scenes many novel systems will operate at scale for the first time and we are bringing a lot of compute up.

It is pure magic.

fun story

recently we weren’t sure if we wanted to ship this and we turned it off internally

and everyone got very very mad

so here we are

[Thomas Ricouard @Dimillian]

And custom sections you make on desktop also sync on Remote!

[Andrew Ambrosino @ajambrosino]

Sidebars!

Custom sections are now in ChatGPT and Codex Desktop! Set up an automation to self-organize. Go nuts.

[Sergii @Rudeg]

Custom sidebar sections just landed in ChatGPT/Codex desktop app 🗂

organize your tasks and projects into sections or just ask codex to organize the sidebar for you!

[Sergii @Rudeg]

@ajambrosino r u going to change your slack pic as well?

@dmfilipenko ???

[Noam Brown @polynoamial]

An internal version of Astra, @OpenAI’s next major model family, solved 10 major open problems in mathematics, quantum complexity, and theoretical computer science.

We believe it will be a major step for scientific reasoning. https://t.co/iP6cyheZ7i

GPT-5.6 has much better taste in frontend work, visualizations, and artifacts.

In the app, you’ll now see more visualizations and interactive tools inline, all generated in real time by 5.6. I’m a visual thinker, so seeing these instead of a wall of text is incredibly refreshing.

- Visualize data with any type of chart
- Learn a topic with interactive walkthroughs
- Explore 3D models
- Walk through steerable simulations
- Use mini-apps to get things done, like sorting through your inbox

Any of these can become a shareable Site with a single click.

If you ever get tired of managing your Codex threads, just let Codex manage itself! Codex can now create threads, search them, organize them, pin the important ones, and spin up worktrees for parallel tasks.

[Theo - t3.gg @theo]

Honestly I'm still really impressed with the Codex app.

It works reliably. It adds useful features consistently. It has taste. The mobile integration is awesome. The git integration is solid.

If you haven't used it yet, I highly recommend it.
